Need to know if the pump I chose is good for regular pumping.

I am a FTM of 1.5 months baby girl. She was in NICU for sometime so I had to start using breast pump.I am currently using luvlap double breast pump but I feel its output is not as expected.I am planning to buy philips one.Can anyone please let me know if philips one is better or same as luvlap? I want it regular pumping.
